Improper capitalization. Use: "Object Class: Safe
I don't see this as a Safe scip, considering the consequence for containing it is the complete destruction of our planet.

Special containment procedures:

Improper capitalization. Use: "Special Containment Procedures:

Scp-XXXX instances are currently uncontained, due to their similarity to baseline terrestrial humans and modern psychology typically designating SCP- XXXX instances as having mild developmental disorders such as [Redacted] [Redacted], and [Redacted].

Capitalize "Scp": "SCP"
This is a run-on. I'd recommend condensing: "SCP-XXXX instances are currently uncontained due to their similarity to baseline humans diagnosed with mental disorders."
There's a lot of bad redaction throughout, so I'll just make the point here: redaction should be used as a narrative device, not just for the sake of redaction. Names, dates, mental disorders, etc. should only be redacted if it's essential to the narrative. I usually recommend that new writers just avoid redaction altogether until they get a better handle on wiki writing. For more information, check the redaction guide.

Due to the risk of provoking violent retaliation from the Scp-XXXX Space Faring Vessels detainment or containment of Scp-XXXX instances can only be approved by unanimous 05 approval.

You need a comma between "vessels" and "detainment".
Redundant use of "approval". Try: "…necessitates unanimous O5 approval".
It's "O5" with the letter O, not "05" with the number 0 (this one confused me too at first).

SCP-xxxx is the collective designation of a Non-terrestrial human species, whom arrived in our Solar system sometime in 19XX.

Delete the comma
"Solar" shouldn't be capitalized.

By unknown means several thousand Scp-XXXX adolescent instances were trans-located from a space faring Vessel, and into terrestrial human households, housing a married infertile couple between the ages of 30-45.

You need a comma after "means".
"trans-located" is weird, I'd use "transported".
"Vessel" shouldn't be capitalized.
Neither comma should be there.

These baseline humans were also, by unknown means transplanted with false memories of adopting and raising the specific Scp-XXXX instance in their household, additionally said SCP-XXXX instances appear to have also either had false memories implanted or are perpetuating a massive disinformation campaign about their appearance on earth.

You need a comma after "means".
This is a run-on. I'd split it up at "additionally".

One patient of mine extended our session to roughly 3 hours as he told me about his favorite cartoon; episode for episode in detail.

Entries are supposed to be impersonal and 3rd person. The in-universe writer shouldn't be referenced.

Conceptually, this is a mixed bag. First off, there's not much in the way of a narrative. Modern scips are expected to have a strong story to go with the anomalous object. There's a good deal of potential here considering the instances are so similar to regular people. A plot involving an instance becoming a senior Foundation member could work, but it's up to you. The biggest concept issue is the lack of an incentive for the Foundation to care. The ship threatening the world with destruction feels a bit shoehorned in. It's also just a "big scary thing that can kill us real good" type object, which feels bland at this point. The destruction of the entire world and everyone on it should be as interesting as it is apocalyptic, and here it just isn't. For more help with concept, I'd check in with the Ideas and Brainstorming forum. All told, the idea has some intriguing aspects, but it needs some development and polish.
Hope I could help, best of luck!

hey thanks for the review ive actually ammended and corrected some of the mistakes you have pointed out, previous to you reviewing my first draft. I would actually appreciate you taking a look at the second draft if you wouldnt mind. honestly the "kill us real good ship", was not shoe horned but if it sounded like that i should really work around it. maybe something about them infiltrating us in some other way would be interesting. thanks for the critique. I will consider making some more changes.
